Remove the last value of an array

Question

I have a basic college project and one of the requirements of the exercise is to remove the last value from an array of integers. I am not able to do with the last value be removed without using an Arraylist, another specification would be not using an Arraylist and using the Pop function for such action, would need a help, because the only method I found would be to replace the last value with 0 and copy that array to a new array, but I think it would not be the most efficient, follow the code with the other functions of the code:

public class Pilha {
    Scanner in = new Scanner(System.in);
    private int top;
    private int[] element = new int[10];
    Pilha(){    
    }

    public int Push(){
            System.out.println("Insira os numeros desejado");
            for(int j = 10; j > 0; j-- ){
                top = in.nextInt();
                element[j-1] = top; 
            }
            return top; 
        }
    public int Pop(){
        return 0;
    }
    public void Show(){
        for(int i = 10; i > 0; i--){
            System.out.println(element[i-1]);
        }
    }
    public void Menu(){
        System.out.println("Digite o que quer fazer");
        System.out.println("Digite 1 para inserir na pilha");
        System.out.println("Digite 2 para remover o  ultimo elemento");
        System.out.println("Digite 3 para mostrar a pilha");
    }
    public void Menu2(){
        System.out.println("Digite o que quer fazer");
        System.out.println("Digite 2 para mostrar a pilha");
        System.out.println("Digite 3 para remover o  ultimo elemento");
    }

Answer 1

As far as I know an Array cannot be resized, so the easiest way to get this control is to create a variable to store which is the last record of the stack.

I used the variable count in the example and it was like this:

import java.util.Arrays;
import java.util.Scanner;

public class Pilha {
    Scanner in = new Scanner(System.in);
    private int top;
    private int count = 0;
    private int[] element = new int[10];
    Pilha(){    
    }

    public void Push(){
            System.out.println("Insira os numeros desejado");
            for(int j = 10; j > 0; j-- ){
                top = in.nextInt();
                element[count] = top;
                count = count + 1;              
            }
            return top; 
        }
    public void Pop(){
        if (count > 0){
            element[count] = 0; //retorna um inteiro nulo para ocupar este espaço
            count = count - 1;
        }
    }
    public void Show(){
        for(int i = count; i > 0; i--){
            System.out.println(element[i-1]);
        }
    }
    public void Menu(){
        System.out.println("Digite o que quer fazer");
        System.out.println("Digite 1 para inserir na pilha");
        System.out.println("Digite 2 para remover o  ultimo elemento");
        System.out.println("Digite 3 para mostrar a pilha");
    }
    public void Menu2(){
        System.out.println("Digite o que quer fazer");
        System.out.println("Digite 2 para mostrar a pilha");
        System.out.println("Digite 3 para remover o  ultimo elemento");
    }
}
